The $99 admission price applies to visitors age 10 and over. Kids ages 3-9 cost $93. At the other theme parks within Walt Disney World -- EPCOT, Disney's Animal Kingdom Park and Disney's Hollywood Studios -- admission has also been hiked by $4. Admission to those parks is $94 for those 10 and up and $88 for kids 3-9.

"Our pricing reflects the high quality and breadth of experiences we offer and our ongoing commitment to investing in our parks," Kim Prunty, a Disney spokeswoman, told ABC News. "We offer a variety of ticket options that provide a great value, and find that most guests select multi-day tickets that offer additional savings."
